I wish to study the mechanics of Bows. I have recently taken up archery and have earned my J.O.A.D. indoor compound white star. I wish to study how different bows work and explain the basics of archery. I will make a 3d representation of the different types of bows, explain how they work and explain the Olympic scoring system.
Sincerely John Boudreau
Notes
Basic mechanics
On all bows exept compounds draw weight increeses as draw lenght increses
The limbs act like springs
Coumpound
Mech. advantage comes from oval shaped cams wich act as levers
recurve
simalar to long bows but curve minamizes brace height and increeses energy use
long
a long bow requires much energy to draw and maximizes arow speed.
short
Shorter draw equils less efort and less speed
composite
Made of diferent materials to increase volocity
arrows
Arrows are usualy made of wood, fiberglass, alluminum, carbon.
the fleching is makes the arrow spin and guides it after twenty yards.
Misc. Equip.
sights aim lowest is for farthes disances
Arm gaurd protects from string lash
finger tabs or cabel realease protect from archers finger
Olimpics
the olimpic scoring sytem has eleven rings the sc ore is counted from inside to out a shot on the line counts for the higher score the center is two yellows an x which is 10 points and a tie breaker the second ring is a ten the next ring is red and the iner is 9 the outer is 8 and it continues blue, black, white. for complete rules visit this website (if you have time by the way the shortest section is 284 pages long.) http://www.usarchery.org/userfiles/file/2008_Rules_Book1.pdf
Glossery
draw length= the distance you must draw a bow into proper position
draw weight= the force required to draw a bow
